A filler pipe 13 closed by a cap 74 comring liquid or medium may consist of '75 parts of municates with the upper side of the chamber peanut oil, 14 parts of rapeseed oil, 1 part of El. The chamber 66 is provided in lower side aluminum stearate and 10 parts of oleic acid. with a drain plug 15. The tank 65 is provided This mixture has a specific heat approximately near its lower end with cold Water inlet nipples 55 l6, and it is provided near its upper end with hot water outlet nipples TI. The nipples l5 and. 17 may be connected by pipes to radiators or the like. Any of these nipples not in use may be closed by caps.

Spiral baiiles '18 are located in and extend throughout the entire length of the fines l E. A gas burner i8 is located in the combustion chamber 69. The burner '59 is supplied with gas through a pipe 89 which extends thereto from a cut-off valve 8! under the control of a thermostat 82 located in the chamber (51. A pilot burner 83 in the combustion chamber 59 is supplied with gas through a tube 85 which is connected to a pipe 85 leading from the source of supply to the valve Bl. The tube 3 3 and the pipe 88 are provided with cut-off valves 86 and 87, respectively.

A pipe 98 extends from the center of the expansion chamber 18 for connection with a chimney. A pipe 89 connected to the upper side of the chamber 6?, and a pipe $9 extending from the side of the tank 5 provide means by which thermometers may be connected to the chamber and tank. A pipe 5! extending from the side of the tank i provides means by which a pressure gauge may be connected to the tank. The heater is mounted on feet 92. The combustion chamber 68 is provided with a door 93.

The chambers 56, 67 and T2 are filled with the heat transferring liquid, as indicated at 94. And the heat transferring liquid is located between the flame of the burner '59 and the water and between the water and the combustion products flowing through the flues H. The heat transferring liquid is also located between the water and the expanding combustion products in the chamber 10.

This heater is also provided with a jacket which surrounds the tank 55 and the chambers 86, 61 and M, and. arranged between these parts and the jacket is a suitable insulating material, not shown.

From the foregoing description, taken in connection with the accompanying drawing, it should be understood that the heater embodies a chamber so arranged with respect to the primary source of heat and the water that the heat transferring liquid is arranged between the primary source of heat and the water, and that, due to its position with relation to the primary source of heat and the water, the heat transferring liquid will transfer substantially all the heat units generated by the primary source of heat to the water. This transfer of the heat units by the heat transferring liquid takes place rapidly, with the result that the water may be raised to the required temperature in a comparatively short time. Furthermore, as the heat transferring liquid transfers substantially all the heat units generated by the primary source of heat, the water may be maintained at the desired temperature at comparatively little expense.
